Chinese and American police forces both operate abroad and like to flex their power. The NYPD was in a similar situation post 9/11 when they started trying to police nearby states and when they sent operatives to other countries even against their own federal government [1].

Russias also sent operatives overseas in some fairly public assassinations. It’s not really surprising that China does this, it appears to be the default operating procedure of powerful countries
